Abstract: Forests play a pivotal role in mitigating climate change by sequestering vast amounts of carbon dioxide from the atmosphere. Large birds, such as hornbills and parrots, perform a crucial ecological function in these ecosystems by dispersing seeds of large-seeded trees. These trees are known for their exceptional carbon storage capacity, contributing significantly to forest carbon stocks. However, the impact of deforestation on the dispersal of these seeds by large birds remains poorly understood.

Introduction: Forests have been recognized as essential carbon sinks, absorbing approximately one-third of human-induced carbon dioxide emissions. Large-seeded trees, dispersed primarily by large birds, exhibit remarkable carbon storage potential. Yet, deforestation poses a significant threat to these forests, jeopardizing the carbon storage services they provide.

The Importance of Seed Dispersal by Large Birds: Large birds play a unique role in seed dispersal due to their ability to consume and transport large seeds over long distances. Their digestive systems are adapted to pass seeds intact, allowing for the germination of viable seedlings at distant locations. The movement of these seeds contributes to genetic diversity and forest regeneration, particularly for species with limited seed dispersal mechanisms.

The Carbon Sequestration Potential of Large-Seeded Trees: Large-seeded trees have inherent characteristics that enhance their carbon storage capacity. Their long lifespans, reaching several centuries, allow them to accumulate substantial amounts of biomass and carbon over time. Additionally, their dense wood and slow decomposition rates contribute to the long-term storage of carbon in forest ecosystems.

The Impact of Deforestation on Seed Dispersal: Deforestation poses a severe threat to the seed dispersal activities of large birds. Habitat loss reduces the availability of nesting and foraging sites, while habitat fragmentation disrupts their movements and foraging ranges. The loss of large birds from forest ecosystems can lead to a decline in the dispersal of large-seeded trees and subsequently reduce forest carbon storage.

Case Studies and Evidence: Numerous studies have demonstrated the positive correlation between the presence of large birds and forest carbon storage. In a study conducted in the Congo Basin, researchers found that areas with high densities of hornbills exhibited higher carbon stocks compared to areas with depleted hornbill populations. Similarly, a study in the Amazon rainforest revealed that the loss of large-bodied parrot species was associated with a decline in the regeneration of large-seeded tree species.

Conservation Implications: Conserving large birds and their habitats is crucial for maintaining forest carbon storage capacity. This can be achieved through measures such as reducing deforestation, implementing sustainable forest management practices, and establishing protected areas that safeguard critical habitats. By protecting these avian seed dispersers, we can ensure the continued dispersal of large-seeded trees and enhance the resilience of forests against climate change.

Conclusion: Large birds play a vital role in enhancing forest carbon storage through their effective dispersal of large-seeded trees. Deforestation poses a significant threat to this ecological function, undermining forest carbon stocks and contributing to climate change. Conservation efforts aimed at protecting large birds and their habitats are essential for mitigating climate change and securing the long-term provision of forest carbon storage services.
